  • Patent number: 11613848
    Abstract: A machine for producing a fibrous web, such as a tissue web, has pressing device with a pressing element and a counter-element with a closed surface for forming a pressure nip. A water-absorbing belt with a web side and an opposite pressing element side is guided together with the fibrous web through the pressure nip and the fibrous web is separated at the end of the pressure nip from the web side of the water-absorbing belt and runs further with the counter-element. The water-absorbing belt has at least a first ply and a second ply, and, as viewed in the thickness direction of the water-absorbing belt, a layer in or on the belt half which faces the pressing element, which layer has a higher specific throughflow resistance than the first ply and/or the second ply.

  • Patent number: 9359723
    Abstract: A machine for producing fiber-containing web material, in particular tissue paper, includes a permeable dewatering belt for transporting fiber-containing source material used for producing web material from a forming section to a suction/pressing section, and a press belt assembly assigned to the suction/pressing section. The source material is received in the suction/pressing section between the press belt assembly and the dewatering belt and the press belt assembly presses the source material and the dewatering belt against a suction assembly of the suction/pressing section. The press belt assembly has a single press belt providing a source material contact surface.

  • Patent number: 7527709
    Abstract: A permeable belt, a belt press including a roll having an exterior surface and the permeable belt, and a method of drying or pressing a web with the permeable belt. The permeable belt has a paper web facing side and is guided over a support surface. The permeable belt can have a tension of between approximately 20 kN/m and approximately 100 KN/m, a permeability value of between approximately 100 cfm and approximately 1200 cfm, a surface contact area of the paper web side that being between approximately 0.5% and approximately 90% when not under tension, and an open area of between approximately 1.0% and approximately 85%. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.

  • Patent number: 7524403
    Abstract: A forming fabric for an ATMOS system or a TAD machine. The forming fabric includes a permeability value of between approximately 100 cfm and approximately 1200 cfm, a paper surface contact area of between approximately 0.5% and approximately 90% when not under pressure and tension, and an open area of between approximately 1.0% and approximately 90%. A belt press for a paper machine can utilize the forming fabric. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.
